The untreated groundwater supply of the Conejo Valley Water Company, located in Thousand Oaks, California, contains excessive sulfides, suspended solids, color, odor, dissolved solids, and certain other undesirable characteristics. Conventional coagulation, sedimentation, and rapid sand filtration practices are not economical in treating the raw water, so it was necessary to develop unusual biologic filtration and long‐period sedimentation procedures. An eventual solution for the Conejo water supply problem was to construct a system to import water through the Metropolitan Water District of Southern California. This system, planned to be in operation in 1963‐64, will serve the entire area and eliminate the need for costly demineralization treatment.
